Questions about 2643.HK
What people ask.
Why is 2643.HK on Broken Stocks?
2643.HK qualifies for the Red List on decline depth. It is down -79.6% from its rolling 252-day high of 64.25 HKD, set on 2025-09-12 — 371d ago.
Is 2643.HK a falling knife?
Not by the strict technical definition. 2643.HK is down -79.6% from its 52-week high, but that high was set 371d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. 2643.HK is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is 2643.HK a buy?
Broken Stocks does not issue buy or sell recommendations. The list is a rules-based technical warning system. It tracks structural decline depth and recency — not company quality, management, fundamentals, or news. Always do your own research and consult a licensed advisor.
Where is 2643.HK trading inside its 52-week range?
At 13.08 HKD, 2643.HK sits 8.3% of the way from its 52-week low (10.82 HKD) to its 52-week high (38.20 HKD). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has 2643.HK been declining?
The current 79.6% decline accrued over 371d, which annualizes to roughly -78.3% per year. Annualized pace is a sanity check — a 30% decline in three months is a different signal than a 30% decline over two years.
